Such thing as too small of AWG? 44?

Let him be right.  And he will be right.  Right up until he throws the power switch and puts 20KV across a bizillion turns of number 44, and melts the wire leading into the coil.  But I think the really, really fun part will be winding a bizillion turns of #44.  Better make a good jig to do that.  I have a hard time with #30.  My current coil that I am playing with only has 3920 turns of #26, and it took me two weeks to build.  Of course it is very large and made from iron pipe.  But you know we were all there once, and someday EvilXBOX will look back and say Doh!

What about your core?  What are you going to use?  What is its saturation point?

Have you ever wound a coil?  Do you know how long it would take you to PROPERLY wind an 8 mile long coil?  100 hours would be a low guess..... IF you could even get a whole coil wound without breaking it (doubtful)

The point is - you can obtain a comparably powerful coil with low power draw using common volts/amps with a manageable wire/coil size.

Start off small - - -

8 miles of #44 x 4?  FORGET IT DUDE - REALLY!!!!!!

BTW: if you calculate the AT from the data you provided:

2000V / 10372000R = 1.928e-4 amps

1.928e-4Ax 40,000 turns = 7.713 Amp-Turns

All of the simple coil examples I gave you BLOW that out of the water and consume about the same amount of power.....( yours .39 watts / 7.7 AT  - mine .44 watts 206 AT)

So for 10% more power I'll get 2900% more Amp-Turns.

Thanks for the link. I had been looking for something like this program on and off for sometime now.
